MEANS FOR MANUFACTURING METAL BARS OR RODS.

SPECIFICATION forming part of Letters Patent No. 494,659, dated April 4,1893.

Serial No. 321,237. (No model.)

To 00% whom it may concern.-

Be it known that I, THEODORE S. VERY, of Boston, in the county ofSuffolk and State of Massachusetts, have invented certain new and usefulImprovements in Means for Mannfacturing Metal Bars, Rods, &c., of whichthe following is a specification.

It is the object of my invention to provide such improvements in themeans for manufacturing metal bars, rods or shafts, railroad rails, &c.,as will enable such articles to be made more expeditiously andeconomically than heretofore.

My invention comprises a mold or former into which the molten metal ispoured or delivered and by which it is slightly chilled and given itsinitial shape, one side of said mold being open and a feeding andcompacting roll located opposite the open side of the mold. From themold the metal passes between rolls which compact it or compress it,giving it its finished form. Both the mold and the rolls may be madehollow so that they may be kept cool by the circulation of watertherein. The form of the mold I make to correspond with the form of thepassage or port between the finishing rolls, so that the work left to bedone by the latter device may be as little as possible.

The invention is well adapted to the formation of horseshoe bars, andwhen it is employed to produce articles of this kind the finishing rollsmay be equipped with devices which will channel the bar and puncture itat the proper point to form nail holes.

My invention will first be described in connection with the accompanyingdrawings and the letters of reference marked thereon, forming a part ofthis specification, and then be pointed out in the claims.

In the said drawings Figure 1- is a perspective sectional View of myinvention and showing the interior construction of the same. Fig. 2- isa plan view of finishing rolls, constructed and arranged to formhorseshoe bars. Fig. 3- is a plan view of rolls calculated to formrailroad rails; and Fig. 4:- is a plan view of cross rolls adapted tothe prod notion of round bars or shafts.

The same letters of reference designate the same parts or featureswherever they occur. a, 1n the drawings, designates a mold or former,preferably made flaring at its upper end to form a kind of hopper intowhich the molten metal may be poured or discharged. The said mold orformer may be hollow so that water may be circulated therein for thepurpose of keeping the mold cool or comparatively cool. As shown in Fig.l, the mold may be provided with an inlet water pipe I), connecting withthe said mold at the bottom and with outlet or overflow pipes c, at ornear the top from which the water may be discharged as it becomes heatedand rises in the mold. The metal, in passing through the mold a, isslightly chilled and given its initial form, and from the said mold ispassed to the finishing rolls d by which it is compacted or compressedand finished. The finishing rolls may be made hollow, as shown in Fig.1, so that water can be circulated therein for the purpose of keepingthe rolls comparatively cool, adapting them to chill the bar or rod ofmetal at the same time that they compact or compress it. If a horseshoebar is to be formed, the aperture of passage between the rolls cl may beof a form suitable to giving the final shape to the bar as it passestherethrough, and one of the rolls may be provided with flange strips e,having on their outer edge prods or pins, f, coinciding with andadapted, in the rotation of the rolls, to enter holes or depressions g,in the other roll, so that the bar will be properly creased andpunctured to make provision for the reception of the shoe attachingnails. 1f the bar is to be formed into a railway rail, the rolls d, willbe so constructed as to make the passage therebetween have the form of arail in cross section, as shown in Fig. 3; and if a round rod or shaftis to be formed, the passage between the rolls may be made round, or thecross rolls h may be employed to act upon the metal after it isdelivered from the mold a, as shown in Fig. 4. In this latter case, therolls will act spirally upon the metal delivered to them, and if needbe, the mold may be rotated in the same direction that the cross rollswill tend to rotate the rod upon which they act, or in a directioncontrary thereto, or it may be maintained in stationary position, ascircumstances and the article to be produced, may suggest.

As before stated, it is preferred to so con- ICO struct the mold a thatit may give a form to the metal passed through it, resembling the shapethat is finally given it by the finishing rolls, and it is desirable toroll the metal in the mold for the purpose of compacting it to a certaindegree, and to feed it forward to the finish rolls. In Fig. 1 I haveshown an arrangement of this character, 21 designating a hollow chillingroll for compressing the metal against the side of the mold a and movingit forward through the latter to the finishing rolls. It is understood,of course, that rolls may be employed intermediate of the mold and thefinishing rolls for working the metal before it is finally treated anddelivered by the finishing rolls, but this, and other variations whichmay be made, in the invention, would not depart from the nature orspirit thereof.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

1. The combination of an initial forming and chilling mold having openends, hollow chilling finishing rolls at the exit end, means for coolingthe rolls and mold, and a roll located one side of the mold between itsends and having its periphery arranged to compact and feed the metal insaid mold, substantially as described.

2. The combination of an initial forming and chilling mold, having anopen side and ends with a roll above said mold for compacting andfeeding the metal forward in said mold, finishing rolls at the exit end,and means for cooling the mold and rolls, as set forth.

In testimony whereof I have signed my name to this specification, in thepresence of two subscribing witnesses, this 13th day of August, A. D.1889.

THEODORE S. VERY.
